METHOD OF PRODUCING GONG STANDS FOR CLOCKS.

Application filed January 20, 1928.

My invention relates to an improved method of producing gong-stands for clocks, the object being to reduce the cost of produc-. ing the same to the minimum.

With these ends in View, my invention consists in a method of producing cast-metal gong-stands consisting in forming the clearance-chamber of the standby coring the same concurrently with casting the stand and then M opera tion for producing an anchoring-bore extending axially from the bottom of the clearancechamber through the opposite wall of the stand to provide for the insertion of theanchoring-tangof the gong.

In the accompanying drawings:

Fig. 1 is a View partly in plan and partly in horizontal section of a gong-stand constructed. in accordance with my invention,

showing two rod-gongs installed therein;

Fig. 2 is a View thereof in side elevation;

Fig. 3 is a front face view of the stand;

Fig. 4 is a view of the standin transverse section, showing the first step in my improved method, which consists in producing the clearance-chamber by coring; and

F 5 is a corresponding view, showing the cored stand after it has been. drilled for the production of its anchoring-bore, this being the second step in my improvedmethod.

Serial No. 248,085.

reception of the flattened anchoring-tang 18,

which is separated from the rod-gong proper 14s by a doubly-beveled reduced portion 15, which prevents the vibrations of the rod from being dampened or-modiiied by the mass of the stand into which a mounting-stud 16 is cast for the purpose of securing the stand to the clock-case; A marked economy in the mass production of such stands is effected by means 01 the method above described. g

1 claim:

A method of producing cast-1netal gongstands consisting in forming the clearancechamberof the stand by coring the same concurrently with casting the stand and then subjecting the cored stand to a drilling operation for producing an anchoring-bore extending axiallyirom the bottom of the clearance chamber through the opposite wall of the stand to proyide for the drive-fit insertion of the anchoring-tang of the said gong.

In testimony whereof, I have signedthis specification. I ELOF 'L. CARLSON.
